Fix the build on 2.13.8 to submit the corresponding graphs:
Remove 2.13.8 in the crossScalaVersions of sbt-dependency-graph
scripted-sbt-redux and scripted-sbt because they
depend on sbtProj.
This removes OkHttp dependency.
This also removes an experimental feature to customize HTTP for Ivy called
CustomHttp we added in sbt 1.3.0.
Since LM got switched to Coursier in 1.3.0, I don't think we advertized
CustomHttp.
Problem
-------
In some situations like Dotty Community Build, sbt version is
mechanically upgraded on an old commit without humans checking the log.
For reasons we're not completely sure (likely change in ClassLoader
structure) sbt 1.6.x started to fail to load test frameworks during
tests, but since the failure of the test framework loading doesn't fail
the task, this silently succeeded the builds.
Solution
--------
On MatchError and NoClassDefFound Error, rethrow the exception.
Note that ClassNotFoundException is considered ok since we have
predefined test frameworks listed in sbt, which often are not included
in the users' classpath.
Fixes https://github.com/sbt/sbt/issues/6558
Problem
-------
sbt uses SecurityManager feature of JDK to trap `sys.exit` call during
`run`-like tasks, since we emulate `run` and `console` as function calls.
JDK 17 deprecated SecurityManager and it's printing warnings.
Solution
--------
About 10 years go, `exit` was a convenient way of quitting both Scala
REPL and sbt shell. Scala 2.11 broke this by removing the `Predef.exit`.
We still need to worry about `run` potentially calling `sys.exit`
but that can be handled using fork feature.
In the long-run, it probably is better to be JDK 17 compatible.
